STM32-SK & AN2557

Hi,

I'm new to the STM32, but I love it. I have the IAR STM32-SK KickStart kit. I was 'playing' with the DMA examples in AN2548, specifically Example1. I modified the code to use AIN15 instead of AIN14 because the IAR board has a Pot on AIN15. The example worked well. But, when I try to reprogram the STM32 with another appl., I get errors from the JTAG/Debugger. The part can not be reprogrammed. I found out if I reprogam the STM32 with the code from AN2557, the In Application Programming example, it works! Then I can reprogram it with what ever I want. Can anyone explain what causes this?

Thanks,

B.K.

Hi,

try to use the latest version of Jlink driver because it implements a new reset type for cortex-M3 devices and may be it fixes your problem.

I can reprogram the STM32 even after loading the code you sent into Flash.

I' using EWARM4.42A+ jlink 3.78a

Here is the project. I modified it to use AIN15 instead of AIN14.
